A handful of engineering problems I've owned end-to-end — infrastructure that was costing more than it earned, performance cliffs hiding under product features, and systems that needed to move faster than a release cycle.
Re-architected data synchronization on a B2B SaaS platform, collapsing 10 Kubernetes pods down to 2 and reducing shared endpoint load by 90%.
Built a high-performance map clustering service for a UK property investment platform, rendering a country-wide dataset at any zoom level in under 100 ms.
Designed a metaprogramming engine that compiled UI-defined rules into executable C# at runtime — collapsing the time-to-market for new pricing rules by 90% and removing the need for code releases.
